The main Battlefield Heroes site has started running contests for a limited number of beta keys. They gave away 400 last night, and there’s more to come. The rumour in the mill is that a large scale beta should be turning up very soon indeed. After the jump we have several minutes of Heroes footage, which starts off fairly slowly – try to imagine it ramped up with eight aside – and then goes fairly triumphant as it shows off the ludicrous air-combat. We get a good glimpse of the pace of the fighting, the layout of one of the maps, the vehicle use, and even some of the character customisations.
